Doctors Office

Hi
Just a question about this plugin: if I install this on a site for a doctor’s office, does it not need to be connected to their current booking system they have in their office, so there are no conflicting appointments?
Probably a very simple question but I’ve just come across this plugin and it looks great! Thanks

Its a pure separate plugin. Appointment Calendar uses its own database and work with them when you installed with your WordPress blog. So, there is no chance to conflicts with current installed booking system.
